TRACK DRAIN.

i .resaca Application filed September To all whom, t may concern.'

Be it known that I, l'VaI/rnn T. @Dorixnnn, a citizen of the UnitedStates, residing at Lakewood, in the county ot' G yahogav and State or'Ohio, havefinvented certain new and useful Improvements in a Tra-ckDrain, of which the following is a specification.

This invention relates to track drains, and the general object of theinvention is to provide a drain box i'or railway tracks which are paved.As constructed the drain box promotes rapid flushing and drainingthrough an inclined discharge opening and connection at one endet thebox and through a straight sloping drain pipe without abrupt crooks orelbows at the box, thereby preventing clogging and making the drain pipeaccessible for inspection and cleansing from the center ot the track,and permitting complementary drain boxes to be used in double trackswith separate drain pipes converging on straight lines from theVseparate drain boxes to a single sewer pipe located centrally betweenthe double tracks.

In the drawing accompanying this application, Fig. l is a plan view or ashort stretch ot' a double-track street railway ernbodying a pair orsetof my improved drain boxes arranged oppositely therein, and Fig. 2 is avertical cross section ot the tracks and drain boxes and their sewerconnections.

Fig. 3 is a vertical section ot one drain box on line 3-3 ot Fig. 2,showing the grid cover raised and unseated. Fig. Ll is a bottoni view ofone of said drain boxes. Fig. 5 is a sectional View of a slightlymodified form of the invention.

I am aware of the use of drain boxes for street railways wherein a sewerconnection is made with an outletcentrally located within the bottom ofthe box and with which it is necessary to use an elbow to eii'ect asewer connection, especially when the main sewer pipe is at one side ofthe track. To overcome vital objections in the actual use et such drainboxes and their connections I provide a drain box 2 ci cast metal whichis relatively narrow and long and comprises fiat studded top ends 3sloping slightly toward the middle chamber portion of the box which hasa depressed border seat i for a removable open grid or cover 5. Thebottom Got the box is inclined downwardly be- Specication of Letterslatent.

ginning at one end and terminating in a rounded outlet T at its oppositeend where a flanged i'lat tace S is formed at a reverse inclination tothe sloping bottom 6 so that a separate short straight pipe extension 9may be bolted thereto at a vertical inclination with the axis thereofextending toward the middle or center of the open upper side of the box.In Fig. 5, outlet extension 9 is shown as integral with the box, but Iprefer using a separable extension affixed to a short flanged outlet forseveral practical reasons. depending apron or flange l0 is also providedat each end of the box which is adapted to. rest upon the base flangesot the railroad rails R to support the box substantially iiush with thepavement, and the bottoin 6 is preferably rounded transversely (see Fig.3) to facilitate drainage and` prevent accumulation ot matter therein.

llhen two suoli drain boxes are placed oppositely in a double trackrailway the outlet ends are placed at the inner sidesof the tracks:facing each other so that separate sewer pipe connections lll-11 may beextended on straight converging lines to and within a stand-pipe or amain sewer connection l2 located centrally beneath and between the pairof tracks.

The line of discharge from each drain box being direct and straight tothe sewer, each line ol pipe can be inspected, reached and cleaned withfacility and despatch by merely removing cover 5, and no accumulation ofmatter or clogging of the box will occur with the inclined out-let 7arranged and constructed as shown.

That I claim is:

l. A track drain, comprising a relatively y and upper open side of saidbox, and a removable grid tor said box.

2. A relatively narrow and long track drain, comprising a cast-metal boxhaving depending supporting walls at its opposite ends and a slopingbottom extending lengthwise of the box and terminating in round outletat one end of said box, said outlet beingextended toward the end oi thebox and downwardly at an inclination rto permit a sewer pipe connectionto be made therewith on a straight line extending toward the middleupper side of Said box.

3. An elongated drain box 'for railway tracks, having a partly open andpartly studded closed top With depending supporting- Hanges at oppositeends thereof and provided with a rounded bottom sloping` doWnwardlytoward one end and terminating in a round outlet and extension projecteddownwardly at an acute inclination to perposed between the paralleltracks thereof.y

each box having a ve1ticallyinclined outlet at its bottoni, and`Separate sewer pipe connections extending from said outlets onystraight coni/erging lines to a common discharge connection locatedcentrally between said double tracks.
